If the light is on the dashboard, you can use your code scanner for hunting down the problem. If the fluid is full and you checked the other things, this would be your next step. Electrical FaultĮlectrical problems can always be to blame, especially if you have a newer power steering system. Usually, a fuse should not blow if there is nothing wrong, but it could simply be the result of a sudden voltage spike.Ĭheck your owner’s manual to find the location of the power steering system fuses in your car.

If you notice that your steering wheel is not straight, even when driving your car straight at higher speeds, or if your car pulls to one side, you may have a wheel alignment problem. If your wheel alignment is very bad, it can trick the computer into thinking the steering angle sensor is the problem, and this will cause the power steering assist error message to appear.

If this sensor goes bad and shows the wrong angle, it will cause the power steering assist error message to appear. To know this, the car uses a steering angle sensor that sits behind your steering wheel. In order for the power steering assist to function properly, it needs to know how much your steering wheel is turned or if it’s straight. RELATED: Power Steering Fluid Colors – What Do They Mean? 2.

Today’s advanced safety features run off of the power steering, which is why the system is so important. Today’s vehicles – especially those that are hybrid – have an electric pump instead that runs off of the battery. Older systems have a belt that connects to the engine to draw energy. As you move the steering wheel, the fluid transfers and creates a force that works to turn the wheels. Hydraulic fluid is found in the reservoir. Instead, an electric pump is used to pressurize the fluid, so steering is made easier. While it still has a hydraulic pump to push fluid, it doesn’t absorb the energy created by the engine as the older types did. Today, we have electric power-assisted steering systems. Since its first introduction, the power steering system has become more advanced. The first model to receive it was the Chrysler Imperial. It wasn’t until 1951 that power steering first showed up in domestic automobiles. In the middle of the 20 th century, you had to muscle the steering wheel of a car to get it to go where you wanted.
